• Silverlight (formerly WPF/E) Getting the id of the hosting WPF/E control

  Hi, The new CTP contains the GetHost method but how can I get the id of the hosting control Lets say I have 2 WPF/E controls on the same HTML implementing the same click event. I need to identify which control was clicked. Thanks, Keren Personally, I couldnt' figure it out. However, I think I figured out a viable workaround. The workaround is as follows: I used the "SourceElement" property of the WPF/E Control to store the id of the hosting control. This approach is probably not optimal, however, because the SourceString and Source property values take precedence in loading XAML content, the approach has worked fine for me. In addition, the "SourceElement" property is just a string and it doe ...Show All

• Visual Studio Tools for Office How do you disable the Close (X) button on a Word application?

• SQL Server Strange behaviour with Sequence Container task

  Hi everyone,   Our VB application throws .dtsx on-demand by using Threads. Everything's fine but a little detail: when it goes to launch a SSIS package with a only task, concretely a Sequence Container task (empty, without tasks inside) fails Prevalidate method.   Attach you the snippet of code:     pkgResults = pkg.Validate( Nothing , Nothing , EventsSSIS, Nothing ) -- pkgResults returns me Failure {1}   If pkgResults = DTSExecResult.Success Then .. ..   Validate method, as usual, do EVENTSSSIS.PreValidate event and after that, returns instead of follow raising events.   Perhaps it's mandatory to set one task as a minimum, I don't get the point at ...Show All

• Visual C# What is "\n"? Any difference from "\r"?

  I know "\r" indicates a sentence break. Then what about "\n" HtmlText = HtmlText.Replace( "\r\n" , "\r" ); HtmlText = HtmlText.Replace( "\n" , "\r" ); HtmlText = HtmlText.Replace( "\r\r" , "<p>" ); HtmlText = HtmlText.Replace( "\r" , "<br>" ); In the above line, since "\r" is to changed into "<br>", why should not directly change "\n" and "\r\n"directly into "<br>" http://west-wind.com/weblog/posts/1499.aspx The 1st statement replaces a DOS end-of-line to a \r, the 2nd replaces a Unix end-of-line to a ...Show All

• Visual C++ How can a C++/CLI library catch unmanaged C++ exceptions from an unmanaged library without breaking the C++ stack unwinding?

  I have a static C++ library, built with VS2005, that is used by multiple projects. The library throws C++ exceptions (derived from std::exception) from its public interface. One project that uses the static C++ library is a .NET class library that is written using C++/CLI. What I have found is that when the .NET class library calls into the unmanaged C++ library and an exception is thrown from within this library, then the application immediately jumps to the .NET class library catch clause without calling unmanaged C++ destructors during stack unwinding. This of course breaks the RAII idiom and is creating a large problem for me. My questions are: Is this expected What is the best solution to work around the problem Many thanks f ...Show All

• SQL Server SqlBulkCopy and Context Connection = T

  I have created an assembly which I load into SQL 2005. However, if I set my connection string = context connection = true... I will get an error saying something like this feature could not be used in this context... So I changed my function to insert each row.... Now the issue I have is the transfer takes 4X as long.... Before I made the change I was using the bulkcopy by specifying the actual connection string....but I also had to specify the password in the string...and since I wanted to get way from this specification...I attempted the context route. So...is there any other way of using the bulkcopy feature or something like it using the context connection Private Shared Function BulkDataTransfer2( ByVal _tblName As String ...Show All

• Visual Studio Express Editions Transparent BMP

  I would like the user to be able to click on one (or more) colors in a .bmp image, which would cause that color (or those colors) to become transparent in the image. The only transparent .bmp color code I have seen is where the programmer specifies that a certain color in a .bmp image will be transparent, which doesn't help to solve my problem. I am very new at this, and any help will be greatly appreciated.   The board add line feeds when it wraps introducing syntax errors until you remove the linefeeds.

It looks very simple until you consider the many, many internal formats of images and then the problem becomes quite complex. ...Show All

• Windows Forms Deployed install wont run application

  Hi folks; I've built a data application in VB 2005 which uses sql 2000 on a remote server. I've created a setup and deployment project in the solution folder for the app -- as explained in the help files walkthrough -- added the dependencies and all the required steps as explained. The application installs and runs perfectly on my development machines, but after installing to a client machine, the exe (or short cut) simply will not initiate the application -- no errors or log info -- when we try to run it.  We get an hour glass icon for a second or 2, then it simply stops without any kind of other behavior.
